Donald Trump is being trolled online after he made another geographical gaffe – this time apparently returning the Mediterranean island of Corsica to Italy.

A map of Trump’s itinerary for his first foreign trip as US President puts the French region of Corsica within Italy’s borders.

Corsica, located west of the Italian Peninsula, has been part of France since 1768 but does maintain many elements of Italian culture. A number of nationalist and independence movements in Corsica continue to oppose French dominance.

The blunder was picked up by Italian social media users who thanked Trump for his oversight.

Local media outlet Corsica Oggi questioned whether Trump wanted to see the Mediterranean island annexed, saying: "Could the American president in reality be an Italian irredentist? Or simply ignorant?"

Of course this isn’t Trump’s first or most significant geographical blunder. After the president arrived in Israel from Saudi Arabia he reportedly said he “just got back from the Middle East.”

Trump, in remarks before meeting with Rivlin, says "we just got back from the Middle East."
